Hy, I’m driving an SJ413 built in 1986 and I’ve prepared it for me for a very long time and now I wanted to increase it by about 4.5cm. Since I’m a little skeptical about the spring leg increase, I wanted to ask you what you think about this kind of increase. The only thing I find positive is that it’s the cheapest kind. I don’t want to spend any more like max 300€ – 400€ for the increase. I would be very happy about your help.
